The Vintage Wrist Watch Company has dated this piece to the 1930s.
J W Benson originated in 1847, founded by James William Benson and Samuel Suckley Benson.
As with many watch manufacturers, J W Benson embraced the newly introduced wristwatch during the first World War. Up until this point, the company was still manufacturing its own movements in the UK but after its factory at Belle Sauvage Yard was hit during a bombing raid in 1914, it purchased mechanisms from a number of quality movement producers in Switzerland.

This particular watch has a Swiss 15-jewel hand-winding movement, signed J W Benson, which is working nicely.
The watch measures 28.5mm wide excluding the winding crown and 28.5mm high excluding the lugs. The case is 9 carat gold and there are hallmarks inside the case back for Glasgow 1930. The front of the case is in good condition. The back has a “ding” and a little unevenness.
The lens is in good condition.
The signed dial is in its original finish. There is a little marking but nothing too serious.
The watch comes in a J W Benson presentation box.
